UNITED STATES SAMUEL HEARONEMUS,

OF SNOVER, MICHIGAN.

SCREW DRIVER.

Application filed March 5, 1923. Serial; No. 622,915.

1/ '0 all whom it may concern Be it known that I, SAMUEL HEARoNE- MUS, acitizen of the United States, residing at Snover, in the county ofSanilac and State of Michigan, have invented a new and useful ScrewDriver, of which the following is a. specification.

This invention relates to screw drivers, and more particularly to thescrew holding type in which the screw is lifted after being removed.

The object of the invention is to provide a simply constructed, cheap,strong device of this character which may be readily manipulated. v

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a side elevation of ascrew driver constructed in accordance with this invention shownapplied;

Fig. 2 is a similar view taken in a plane at right angles to Fig. 1; and

Fig. 3 is a transverse section through the body member of the tool.

In the embodiment illustrated, the tool constituting this inventioncomprises a body member 1 which is here shown cylindrical and of uniformdiameter throughout, being provided at its front end with a screwengaging point or blade 2 and equipped in its opposite faces at a pointspaced from said end with longitudinally extending grooves 8 and 4.

This body member 1 may be equipped with any suitable form of handle 5composed of wood or other material.

The screw-holding device which constitutes a part of the inventioncomprises a sleeve 6 which encircles and is slidably mounted on the body1 and is equipped with rearwardly extending longitudinal fingers 7 and 8having inturned lips 9 at their rear ends which enter grooves 3 and 41said grooves forming guides for said fingers and holding the sleeveagainst turning on the body 1.

This sleeve 6 is provided at its front end with longitudinally extendingfingers 10 and 11 provided at their free ends with inturned lips 12which engage the shoulders 13 formed at the base of the kerf-engagingblade 2 and limit the rearward movement of the sleeve.

A coiled spring 14: encircles the body 1 with one end engaging thefingers 7 and 8 and its other end secured to the member 1 in anysuitable manner and exerts its tension to force the screw holder 6backward so that when the lips 12 of the front fingers 10 and 11 areengaged with the beveled head H of the screw S, the screw will beheldbetween said lips and the blade 2 which is inserted in the kerf of thescrew so that the screw may be lifted out when removed, and will be heldby the screw driver until manually released.

In the use of this screw driver, the screw holding device 6 is movedforwardly against the tension of spring 14 a suflicient distance tooperate the lips 12 of fingers 10 and 11 to receive between them and theblade 2 the. head H of the screw which is engaged by slipping thesefingers sidewise over said head. The blade 2 is inserted in the kerf ofthe screw and the turning of the screw driver will operate to unscrewthe screw, which may be lifted out of its socket by the holder 6. Thistool may also be used for inserting a screw, it having been firstengaged by slipping the leaves 12 over the head and screwing the screwinto place.

Various changes in the form, shape, proportion and other minor detailsof construction may be made without departing from the principle orsacrificing any of the advantages of the claimed invention.

I claim A tool of the class described comprising a body member havingdiametrically opposite longitudinally extending grooves therein with akerf-engaging blade at its front end having shoulders at its base, ascrew holder in the form of a sleeve snugly fitting said body andslidable thereon and having rearwardly extending fingers with lips attheir free ends engaging said grooves whereby the holder is held againstturning on the body, and an intermediate olfset portion embracing acoiled spring on said body to hold the sleeve normally in retractedposition, longitudinally extending fingers at the front of said sleeve,said fingers being in alinement with said first mentioned fingers andhaving inturned lips at their free ends to cooperate Withsaid. blades toc-lampingly clamp the head of the screw between them forming a threepoint screw holder, said lips engaging the shoulders at the base of saidblade when the sleeve is in retracted position with the fingers fittingclosely against the body member.
